These are reserved registers and should not be accessed.

27:31 WINSIZE Window Size - Defines the size of window. The lower bits of WINBASE are effecttively
ignored/masked from snooping address comparison depending on the value set in this field.
WINSIZE = 00000: Window miss*
WINSIZE = 00001 - 01011: 4KByte (non-mask)
WINSIZE = 01100: 8KByte (1 bit mask)
WINSIZE = 01101: 16KByte (2 bits mask)
WINSIZE = 01110: 32KByte (3 bits mask)
WINSIZE = 01111: 64KByte (4 bits mask)
WINSIZE = 10000: 128KByte (5 bits mask)
WINSIZE = 10001: 256KByte (6 bits mask)
WINSIZE = 10010: 512KByte (7 bits mask)
WINSIZE = 10011: 1MByte (8 bits mask)
WINSIZE = 10100: 2MByte (9 bits mask)
WINSIZE = 10101: 4MByte (10 bits mask)
WINSIZE = 10110: 8MByte (11 bits mask)
WINSIZE = 10111: 16MByte (12 bits mask)
WINSIZE = 11000: 32MByte (13 bits mask)
WINSIZE = 11001: 64MByte (14 bits mask)
WINSIZE = 11010: 128MByte (15 bits mask)
WINSIZE = 11011: 256MByte (16 bits mask)
WINSIZE = 11100: 512MByte (17 bits mask)
WINSIZE = 11101: 1GByte (18 bits mask)
WINSIZE = : 2GByte (19 bits mask)
WINSIZE = 11111: Reserved
Note: *NOTE: Software should always write a non-zero value in this field. Otherwise, the
address comparison does not take effect (treated as a “window miss”).
